Encrypter is a simple Java class for encrypting a java object to text, and later reversing the process. It's useful for transferring sensitive data over an unencrypted channel, such as in an XML document or email.

DES encryption is performed using Java's SealedObject class, and Base64 encoding is handled by the public domain Base64 class.

The archive contains the original source code (in src/main/java), JUnit unit tests in (src/test/java) and the complied .jar (at target/Encrypter-X.X.jar).

Examples

Here's an example of instantiating Encrypter, encrypting an object to a String, and decrypting a String to an object. Typically, the encrypting and decrypting would be called in separate places and not one after another as in this example.

package com.arc90.example;

import java.util.ArrayList;
import java.util.List;
import com.arc90.labs.encrypter.Encrypter;

/**
 * Example usage of the Encrypter class
 */
public class EncrypterExample
{
	public static void main(String[] args)
	{
		String password = "cW1dm0re";
		
		/*
		 * Create the object to encrypt (must be Serializable)
		 */
		List secrets = new ArrayList();
		secrets.add(4);
		secrets.add(8);
		secrets.add(15);
		secrets.add(16);
		secrets.add(23);
		secrets.add(42);
		
		/*
		 * Encrypt the object into a String named cipherText
		 */
		Encrypter> encrypter = new Encrypter>();
		String cipherText = encrypter.encryptAndSerialize(secrets, password);
		
		/*
		 * Print the encrypted String
		 */
		System.out.println(cipherText);
		
		/*
		 * Decrypt the String
		 */
		List reversed = encrypter.deserializeAndDecrypt(cipherText, password);
		
		/*
		 * Print the decrypted object
		 */
		for(Integer i : reversed)
		{
			System.out.println(i);
		}
	}
}
